^Uriel I reckon.

I got a Holy Steel Argentum and am considering using it on my 2-star Lazy Bow Hail Punisher to get it to FLB range. Should I do that or wait until the Sloth Union Event re-runs and save the Holy Steel Argentum in case I rack up copies of an SSR Gacha weapon? I'm hoping that by the time the Sloth event re-runs our Union would be strong enough to get four copies of that or whatever FLB weapons are available to have extra copies for Phantom Weapons and such.
